Dedicated Attorney John B. Brennan Provides Focused Representation in Burlington County, Camden County, Gloucester County, and Throughout New Jersey

If you or a loved one are being investigated for committing a crime or have already been placed under arrest and subject to criminal charges, you need the right criminal defense attorney to ensure that your rights, interests, and freedom are protected. But picking the right criminal defense lawyer for you and your case can be incredibly difficult, especially when you have many criminal defense lawyers and law firms to choose from in South Jersey. When you choose me to represent you in your criminal case, you’ll not only get the advice and assistance of an attorney with years of experience in the New Jersey criminal justice system; I’ve spent 25 years serving as a prosecutor in the state, so I have a unique perspective on how the state prosecutes criminal charges and I will use that knowledge to help build an effective legal defense strategy to get you the best possible outcome in your case. And you can also rest assured that an attorney is personally handling every aspect of your case. I also strive to maintain open communication with clients, promptly returning all calls and emails so that your questions are answered and you stay updated on the progress of your case.

I recognize that facing criminal charges may be one of the most important and stressful events you will go through in your life.  I have the compassion, knowledge and experience necessary to ensure you receive the most favorable resolution to your criminal charges, whether that be negotiating with the prosecution for a favorable deal or developing an aggressive legal defense to challenge the state’s case and have your charges reduced or dismissed. I know that your reputation, freedom, and future are at stake when you’re being investigated or have been arrested for a crime in New Jersey, which is why I focus on getting you the results you deserve in your matter.

Whether you’ve been arrested for a simple matter like a first-time DUI or possession of marijuana, or for a more serious crime like assault or weapons charges, let me put my experience and knowledge to work for you, helping guide you through the criminal justice process.

Extensive Legal Experience

Having spent 25 years serving as a criminal prosecutor, I’ve seen how the state builds criminal cases because I’ve done it myself, so I know exactly how to challenge the admissibility and sufficiency of the state’s evidence and case to get your charges reduced or dismissed. 

Certified Legal Counsel

I am a Certified Criminal Trial Attorney and a member of the New Jersey Association of Criminal Defense Lawyers, which reflects my extensive background in and professional commitment to working in the criminal justice system.

When you’re under investigation or arrest, you need to know what your legal rights and options are to begin making important decisions that will affect your freedom and future. That’s why I offer free initial consultations where I can give you an honest assessment of the best possible outcomes in your case.

Whether you have been charged with a felony or a misdemeanor, the resolution can affect your entire future, from your life to your family and finances. At The Law Office of John B.

Criminal Defense Firm Represents Clients Facing Serious Charges in New Jersey

With decades of experience in the New Jersey criminal justice system, including 25 years serving as a prosecutor, I’ve had broad exposure to all kinds of criminal cases in Burlington, Camden, and Gloucester counties and all surrounding areas. That’s why I can provide you with the skilled legal representation you need to face your criminal charges head-on and protect your reputation and future by staying out of prison and getting back to your normal life as soon as possible.

Due to my extensive background, I know what it takes to challenge the state’s case, including having the state’s evidence excluded from your case or challenging the sufficiency of the state’s case to have your charges reduced or even dismissed outright. Depending on the circumstances of your case, I can also help you explore alternatives to prosecution and conviction, including pre-trial intervention programs, conditional dismissal, or conditional discharge.

When your reputation, freedom, and future are at stake, you need a criminal defense attorney who will go the extra mile to ensure you get the best possible outcome in your case. You can also trust that I will never pressure you to accept a plea bargain just to resolve your case; instead, I will fight  to get your charges reduced or dismissed or to secure an acquittal at trial, including seeking to exclude state’s evidence obtained in violation of your civil and constitutional rights, vigorously cross-examining the state’s evidence and witnesses, and ensuring that during the course of the prosecution and trial your rights are protected and observed by the prosecution and by the court.
